TAIPEI (Taiwan News) — Chi Mei Medical Center said Thursday that a 20-year study by its team found monthly antibiotic injections can significantly lower the risk of repeated cellulitis infections, CNA reported.

At a press conference, Chen Hung-jui (陳宏睿), an infectious disease specialist at the hospital, said that cellulitis is mainly caused by bacteria entering the tissue under the skin through wounds. Common symptoms include redness, swelling, and pain, and the infection can worsen into sepsis if not treated promptly. 

According to Taipei Veterans General Hospital, typical treatment includes oral antibiotics and keeping the affected area clean and dry. If an abscess or tissue death occurs, surgery may be needed to drain the infection or remove dead tissue.

The hospital said 426 people with repeated cellulitis infections participated in the study. They received monthly antibiotic injections, and the number of repeated infections fell significantly as the treatment helped suppress bacteria and prevent the infection from worsening, Chen noted.

Chen highlighted the importance of identifying the causes of repeated cellulitis infections. He warned the condition can return even after the treatment is completed if the root cause is not addressed.

People with poor blood circulation face a significantly higher risk of cellulitis returning, Chen added. High-risk groups also include those with diabetes, obesity, or weakened immune systems.

Doctors will assess blood vessels in people with repeated cellulitis infections. Chen said that blocked arteries require procedures to improve blood flow, while blood clots in veins can be treated with blood thinners to improve circulation.

Chen urged people with repeated cellulitis to get the monthly injection, noting that it is covered by National Health Insurance.
